Combining partial correlation and an information theory approach to the reversed engineering of gene co-expression networks.

Bioinformatics 24(21):2491-7 (2008) PMID 18784117

We present PCIT, an algorithm for the reconstruction of gene co-expression networks (GCN) that combines the concept partial correlation coefficient with information theory to identify significant gene to gene associations defining edges in the reconstruction of GCN. The properties of PCIT are examined in the context of the topology of the reconstructed network including connectivity structure, clustering coefficient and sensitivity.
